Description

本発明は、請求項１の上位概念に記載の車両座席に関する。  The present invention relates to a vehicle seat according to the superordinate concept of claim 1.

このような座席は、ドイツ連邦共和国特許出願公開第１９８８２４１３号明細書から公知である。この車両座席は、ほぼ直立するか又は少し後方へ傾斜する背もたれを持つ使用位置と、一部前方へ倒される背もたれ及び縦方向に前方へ縦方向へ移動される座枠を持ちかつ後部座席への簡単な入り込みを可能にする簡単入り込み位置又は出入り容易位置との間で、可動である。このため背もたれと座枠との間の傾斜調節器の解錠が、上部操作レバーを介して行われる。  Such a seat is known from DE 198 24 413 A1. This vehicle seat has a use position with a backrest that is almost upright or inclined slightly rearward, a backrest that is partly tilted forward, and a seat frame that is moved longitudinally forward in the vertical direction and to the rear seat. It is movable between a simple entry position or an easy entry / exit position that allows easy entry. For this reason, the tilt adjuster between the backrest and the seat frame is unlocked via the upper operation lever.

ドイツ連邦共和国特許第１００４３４０４号明細書は、倒すことができる背もたれ用の係止装置を持つ車両座席を示しており、この背もたれは前方へ出入り容易位置へ前倒し可能であり、この位置で係止可能であり、その際背もたれ側係止突起が、ばねを介して背もたれに結合されている相手素子の溝範囲へ係合する。背もたれの前倒しの際、ローラが溝範囲へ達して、それ以上の前倒しを阻止する。  German Patent No. 10043404 shows a vehicle seat with a locking device for the backrest that can be tilted, which can be moved forward and forward to an easy position and locked in this position. In this case, the back-side locking projection engages with the groove region of the mating element connected to the backrest via a spring. When the backrest is moved forward, the roller reaches the groove area to prevent further forward movement.

国際公開第ＷＯ９９／３８７２３号は、背もたれの上部範囲に取付けられる２つのハンドルを介して出入り容易位置及び積み荷位置へ可動な車両座席を示している。この場合出入り容易位置において、背もたれが一部前倒しされている。  International Publication No. WO 99/38723 shows a vehicle seat that is movable to an easy access position and a loading position via two handles attached to the upper area of the backrest. In this case, the backrest is partly moved forward at the easy access position.

車両座席の縦方向移動のため、一般に座枠に固定した上部レールが設けられて、車両に固定した下部レール上を滑る。この場合強度上の理由から、使用範囲においてある程度の最小長さで上部レールと下部レールの重なりが必要である。後部座席へ楽に入るため座席を更に前方移動すると、レールの重なりが減少し、その際減少したレール重なりは空の座席を支持するには充分であるが、そこの座席は走行運転のため利用者が利用してはならない。  In order to move the vehicle seat in the vertical direction, generally, an upper rail fixed to the seat frame is provided and slides on the lower rail fixed to the vehicle. In this case, for reasons of strength, it is necessary to overlap the upper rail and the lower rail with a certain minimum length in the use range. Moving the seat further forward to make it easier to enter the rear seat reduces the rail overlap, which is sufficient to support the empty seat, but the seat is used by the user for driving. Should not be used.

しかし最初にあげた車両座席は、出入り容易位置における車両座席の権限のない利用に対して僅かな安全性しか持っていない。若干の車両座席では、出入り容易位置で利用者は、ハンドルの操作により背もたれを後方へ揺動することができるので、利用者は、後方揺動される背もたれと前部座席又はかじ取りハンドルとの間に、座席上に原則的に充分な場所を持っている。従って走行運転において、許されない利用が行われることがある。例えばドイツ連邦共和国特許第１００４３４０号明細書に示されているように、係止装置も前倒し位置にある背もたれの完全な鎖錠を保証できないので、利用者は誤操作の際背もたれを大きい力により後方へ倒すことがある。  However, the first mentioned vehicle seat has little safety against unauthorized use of the vehicle seat in the easy access position. In some vehicle seats, the user can swing the backrest backward by operating the handle, so that the user can move between the backrest that is swung back and the front seat or steering handle. In addition, in principle there is enough space on the seat. Therefore, there is a case where unauthorized use is performed in traveling operation. For example, as shown in German Patent No. 10034040, the locking device cannot guarantee a complete locking of the backrest in the forward position, so that the user can push the backrest backward with great force in the event of an operation error. May be defeated.

本発明の課題は、出入り容易位置における車両座席の権限のない利用を少なくとも大幅に防止するか、又は困難にすることである。  It is an object of the present invention to at least greatly prevent or make difficult the unauthorized use of a vehicle seat in an easy access position.

この課題は、請求項１に記載の車両座席により解決される。従属請求項は好ましい展開を示している。  This problem is solved by the vehicle seat according to claim 1. The dependent claims show preferred developments.

従って本発明によれば、座枠が縦方向に前方へ動かされかつ背もたれが一部前方へ倒されている出入り容易位置において、座枠に取付けられた係止手段及び背もたれに形成される係止部により、背もたれの後倒しが防止される。この場合係止機構は、座枠の縦方向位置に関係して自動的に動き、座枠の後部使用範囲において釈放位置を、また座枠の前部出入り容易範囲において拘束位置又は係止位置を、確実にかつ誤操作の可能性なしにとる。  Therefore, according to the present invention, the locking means attached to the seat frame and the locking formed on the backrest in the easy-in / out position where the seat frame is moved forward in the vertical direction and the backrest is partially tilted forward. The part prevents the backrest from being tilted back. In this case, the locking mechanism automatically moves in relation to the vertical position of the seat frame, and sets the release position in the rear use range of the seat frame, and the restraint position or the lock position in the front entrance / exit range of the seat frame. Take it reliably and without the possibility of misoperation.

係止機構は当接手段例えばローラをもつことができ、このローラは、使用範囲において、車両に固定した相手片例えば棧片へ取付けられ、前部出入り容易範囲において、自由に走行するか、又は車両に固定した相手片との接触を解除される。前部出入り容易範囲において当接手段が接触しなくなると、予荷重を生じるばねを緩めながら、係止機構の係止手段例えば当接手段と伝動結合されている当接レバーの係止頭部が、背もたれの係止部へ係合する。しかし本発明によれば、逆の構成も原則的に可能であり、前部出入り容易範囲において当接手段が、車両に固定した相手片へ取付けられ、使用範囲において接触しなくなり、それにより使用範囲にある係止手段が係止部から外れる。  The locking mechanism can have abutment means, for example a roller, which in the range of use is attached to a mating piece fixed to the vehicle, for example a saddle piece, and runs freely in the front entry / exit range, or The contact with the opponent piece fixed to the vehicle is released. When the contact means does not come into contact in the front easy access range, the locking head of the contact lever that is connected to the locking means of the locking mechanism, such as the contact means, is loosened while loosening the spring that generates the preload. Engage with the locking part of the backrest. However, according to the present invention, the reverse configuration is also possible in principle, and the abutting means is attached to the mating piece fixed to the vehicle in the easy to enter / exit range, so that it does not contact in the use range, thereby The locking means located at the position is released from the locking portion.

前部出入り容易範囲において、縦方向移動の鎖錠が行われないと有利である。  It is advantageous if the longitudinal movement is not locked within the easy access range.

添付図面により、本発明の実施例が説明される。  Embodiments of the present invention will be described with reference to the accompanying drawings.

車両の第１列又は第２列の車両座席１は、（走行方向において）別の車両座席２の前に設けられている。後部の車両座席２へは、車両座席１と同じ扉を経て利用者が達し、そのためこの車両座席１を適当に動かさねばならない。  A vehicle seat 1 in the first or second row of vehicles is provided in front of another vehicle seat 2 (in the direction of travel). The user reaches the rear vehicle seat 2 through the same door as the vehicle seat 1, and therefore the vehicle seat 1 must be moved appropriately.

車両座席１は、アダプタ片４を持つ座枠３と上部レール５とを持ち、この上部レール５が、車両に固定した下部レール６上を、後部使用範囲内で縦方向に動かされ、拘束されることができ、更に前部出入容易範囲へ移動可能である。  The vehicle seat 1 has a seat frame 3 having an adapter piece 4 and an upper rail 5, and the upper rail 5 is moved and restrained in a vertical direction within a rear use range on a lower rail 6 fixed to the vehicle. It is possible to move to the front entry / exit range.

更に車両座席１は、座りクッション７と、背もたれ揺動軸Ａの周りに傾斜可能にアダプタ４に設けられる背もたれ８とを持っている。背もたれ８は、傾斜調節器を介してアダプタ４に拘束され、座りクッション上に座る利用者により、例えば背もたれ８の下部範囲に設けられる操作レバーを介してこの拘束を解除することができるので、利用者は背もたれ８を例えば背中によりばね力に抗して後方へ押すことができる。  Further, the vehicle seat 1 has a seat cushion 7 and a backrest 8 provided on the adapter 4 so as to be tiltable around the backrest swinging axis A. The backrest 8 is restrained by the adapter 4 via the tilt adjuster, and can be released by the user sitting on the seat cushion, for example, via an operation lever provided in the lower range of the backrest 8. A person can push the backrest 8 backward, for example, against the spring force by the back.

図１に示す車両座席の使用位置では、座枠３は走行方向において後部の使用範囲にあり、この使用範囲内で、座りクッション７上に座る利用者により座枠３を調節することができる。  In the use position of the vehicle seat shown in FIG. 1, the seat frame 3 is in the use range at the rear in the traveling direction, and the seat frame 3 can be adjusted by a user sitting on the seat cushion 7 within this use range.

更に背もたれ８の上部範囲に、図示してないハンドルが設けられ、このハンドルにより背もたれ８の傾斜調節器を解除し、またこれと組合わせて下部レール６上における上部レール５の縦方向拘束を解除することができる。  Furthermore, a handle (not shown) is provided in the upper range of the backrest 8, and the tilt adjuster of the backrest 8 is released by this handle, and in combination with this, the vertical restraint of the upper rail 5 on the lower rail 6 is released. can do.

アダプタ４には係止機構９が取付けられて、図１及び２に示す使用位置から図３及び４に示す出入り容易位置へ座枠３の縦方向移動の際、係止機構９が釈放位置から拘束位置へ自動的に動かされる。係止機構９は、揺動軸受１０を介してアダプタ４に枢着される係止レバー１１を持ち、この係止レバー１１の上部レバー腕は、ほぼ上方へ向く係止頭部１２を持ち、その下部レバー腕は、枢着点１３で、伝達部材として役立つ棒１６に結合されている。更に係止レバー１１の下部レバー碗には引張りばね１８が作用して、係止レバー１１を図３及び４の拘束位置へもたらすように予荷重をかけている。棒１６の前端は、枢着点２０において、揺動軸受２１を介してアダプタ４に枢着される当接レバー２２の上部碗に枢着されている。当接レバー２２の前部レバー碗の前端にはローラ２４が支持され、ばね１８により生じる予荷重によって、下部レール６に取付けられて使用範囲内で縦方向に延びる棧片２５上へ押付けられ、座枠３の縦方向移動の際この棧片２５上をころがる。車両に固定した棧片２５は、その前端に、既に出入り容易範囲へ移行して下方へ下降する傾斜部２８を持っている。  A locking mechanism 9 is attached to the adapter 4 so that when the seat frame 3 is moved in the vertical direction from the use position shown in FIGS. 1 and 2 to the easy entry / exit position shown in FIGS. It is automatically moved to the restraint position. The locking mechanism 9 has a locking lever 11 pivotally attached to the adapter 4 via a rocking bearing 10, and the upper lever arm of the locking lever 11 has a locking head 12 that faces substantially upward, Its lower lever arm is connected at a pivot point 13 to a bar 16 which serves as a transmission member. Further, a tension spring 18 acts on the lower lever rod of the locking lever 11 to apply a preload so as to bring the locking lever 11 to the restraining position shown in FIGS. The front end of the rod 16 is pivotally attached at the pivot point 20 to the upper collar of the contact lever 22 pivotally attached to the adapter 4 via the swing bearing 21. A roller 24 is supported at the front end of the front lever rod of the contact lever 22, and is pressed onto a rod piece 25 which is attached to the lower rail 6 and extends in the vertical direction within the range of use by a preload generated by the spring 18. When the seat frame 3 is moved in the vertical direction, it rolls on the flange 25. The flange 25 fixed to the vehicle has an inclined portion 28 at the front end thereof that has already shifted to the easy entry / exit range and descends downward.

背もたれ８又はその背もたれ枠のほぼ円状に推移する下部外側輪郭３０に、出入り容易位置において係止頭部１２を受入れるための半径方向凹所としての係止部３２が形成されている。  A locking portion 32 is formed as a radial recess for receiving the locking head 12 in the easy-out position in the lower outer contour 30 of the backrest 8 or its back frame that changes in a substantially circular shape.

アダプタ４の上部範囲の外側輪郭３４には切欠き３５が形成され、背もたれ８又は背もたれ枠に取付けられて横方向に突出するピン４０がこの切欠き３５内で自由に揺動する。切欠き３５は、前部の出入り容易ストッパ３６と快適範囲の後端部を規定する後部ストッパ３７とにより限定されて、背もたれ８の揺動範囲を規定する。  A cutout 35 is formed in the outer contour 34 of the upper region of the adapter 4, and a pin 40 attached to the backrest 8 or the backrest frame and projecting in the lateral direction freely swings in the cutout 35. The notch 35 is limited by the front entrance / exit easy stopper 36 and the rear stopper 37 that defines the rear end of the comfortable range, and defines the swing range of the backrest 8.

図１の使用位置において、ばね１８が当接レバー２２のローラ２４を相手片２５としての棧片２５へ押付け、それにより係止レバー１１のそれ以上の揺動が阻止される。従って係止レバー１１の係止頭部１２は、背もたれ８の係止部３２に係合しないので、傾斜調節器の釈放後背もたれ８は、ストッパ３６，３７により規定される揺動範囲内で揺動可能である。  In the use position of FIG. 1, the spring 18 presses the roller 24 of the contact lever 22 against the flange 25 as the mating piece 25, thereby preventing further swinging of the locking lever 11. Therefore, the locking head 12 of the locking lever 11 does not engage with the locking portion 32 of the backrest 8, so that the backrest 8 after the release of the tilt adjuster swings within the swing range defined by the stoppers 36 and 37. It is possible to move.

図３及び４に示す出入り容易範囲へ車両座席を動かす際、利用者は、背もたれ８の上部範囲に設けられる操作レバーを介して傾斜調節器を釈放し、背もたれに固定したピン４０が前部ストッパ３６へ達するまで、背もたれ８をまず前方へ倒す。続いて利用者は、同じ運動で、車両座席１を、下部レール６上で縦方向前方へ、使用範囲を越えて移動することができる。この場合ローラ２４は棧片２５からその傾斜部２８を越えて、ばね１８を緩めながら下方へ達する。これによりばね１８は係止レバー１１を引張るので、係止レバーの係止頭部１２は上方へ係止部３２の中へ揺動される。  When the vehicle seat is moved to the easy access range shown in FIGS. 3 and 4, the user releases the tilt adjuster via the operation lever provided in the upper range of the backrest 8, and the pin 40 fixed to the backrest has the front stopper. The backrest 8 is first pushed forward until reaching 36. Subsequently, the user can move the vehicle seat 1 forward in the vertical direction on the lower rail 6 beyond the use range in the same motion. In this case, the roller 24 reaches the lower side while loosening the spring 18 over the inclined portion 28 from the flange piece 25. As a result, the spring 18 pulls the locking lever 11, so that the locking head 12 of the locking lever is swung upward into the locking portion 32.

背もたれ８の揺動運動、従って図３の出入り容器位置からの背もたれ８の戻し倒しも、はまり合いで確実に阻止されるので、背もたれの戻し倒しのために利用者は、まず再び車両座席１を出入り容易範囲から快適範囲へ縦方向に後方へ移動せねばならない。この場合ローラ２４は、棧片２５の傾斜部２８へ達し、更に後方移動の際持上げられ、続いて棧片２５上を滑る。傾斜部２８は、従って後方へ移動するローラ２４を受けるのに役立つ。それに応じて係止レバー１１は揺動軸受１０の周りに反時計方向に揺動されるので、係止頭部１２は係止部２２から外れて、背もたれ８を釈放する。  Since the swinging motion of the backrest 8, and thus the backrest of the backrest 8 from the position of the entrance / exit container shown in FIG. You must move backward from the easy access area to the comfort area in the vertical direction. In this case, the roller 24 reaches the inclined portion 28 of the flange piece 25 and is further lifted during backward movement, and then slides on the flange piece 25. The ramp 28 thus serves to receive the roller 24 moving backwards. Accordingly, the locking lever 11 is swung counterclockwise around the rocking bearing 10, so that the locking head 12 is disengaged from the locking portion 22 and releases the backrest 8.
